10 Claims. (Cl. 19-159) This invention relates to a coiler mechanism andhas particular relation to a coiler mechanism wherein a sliver ofmaterial is coiled into a rotatably mounted sliver can.

According to the present invention an improved turntable arrangement fora coiler mechanism is provided wherein a sliver can is rotatably mountedbeneath a coiler head to receive a sliver therefrom which is coiledsymmetrically within the can. In the present invention the sliver can ismounted on a turntable which is rotated by means of a novel drivingarrangement. The present invention contemplates improved driving meansforA the turntable whereby the latter can be adjusted in a horizontaldirection relative to the coiler head in order to permit various sizedsliver cans to be properly positioned with respect to the coiler head.The turntable drive includes also improved means for permitting areversal in t-he direction of rotation of the turntable.

The improved drive means for the turntable includes a worm shaft whichmeshes with a worm gear secured to the turntable. The worm gear andturntable are rotatably supported by a bearing assembly which isadjustably secured to a base assembly. The bearing assembly togetherwith the turntable may be adjusted to selected positions spaced in adirection parallel to the worm shaft.`

An object of the invention is to provide a coiler mechanism having arotatable turntable for supporting a sliver can beneath a coiler headwith improved driving means for rotating the turntable.

Another object of the invention is to provide a coiler mechanismincluding a rotatable turntable for supporting a sliver can beneath acoiler head with improved driving means for the turntable providing foradjusting the turntable in a horizontal direction relative to the coilerhead to enable different diameter cans to be used and which will becorrectly positioned relative to the coiler head.

It is a further object of the invention to provide a mechanism asdefined in the preceding object wherein the driving means includes anovel arrangement for permitting a reversal in the direction of rotationof the turntable.

Other objects of the invention will become apparent from the followingdescription taken in conjunction with the accompanying drawings formingpart of this specification, in which Fig. 1 is a view in elevtion of acoiler mechanism embodying the teachings of the present invention;

Fig. 2 is a view taken along the line 2-2 of Fig. 3 with parts shown insection illustrating the driving mechanism for'rotating the turntable;

Fig. 3 is a partly sectional and plan view taken along the line 3-3 ofFig. 2 with certain parts broken away;

Fig. 4 is a view in section taken along the line 4-4 of Fig. 3; and

Fig. 5 is an elevational sectional view showing the idler shaft and gearforming a part of the driving mechanism.

Referring now to the drawings, there is illustrated in Fig. 1 a coilermechanism for coiling a sliver of fibrous maare iiiatt rjce terial intoa sliver can in a symmetrical manner so that the coiled material mayreadily be withdrawn from the can. The coiler mechanism includes acoiler head 1 which may be of conventional construction and which issupported at the upper end of a vertically extending hollow column 2,secured at its lower end to a base 3. The base 3 is adapted to rest upona supporting surface such as a floor. The coiler mechanism also includesa turntable 4 which is arranged to support a sliver can 5 illustrated inFig. 1 as extending upwardly from the turntable with its open enddirectly beneath the head 1. The turntable 4 is rotatably supported bythe base 3 in a manner presently to be described.

The turntable 4 is rotated from a transmission yarrangement which isdriven from an input shaft 6 shown in Fig. 2 as extending horizontallyinto the hollow of the column 2. The input shaft 6 is conventionallydriven through a drive D from a carding or other textile machine withwhich'the coiler is being used. As illustrated in Fig. 2, the shaft 6drives a transmission 7 within the hollow of the column which isdrivingly connected to suitable gearing Salso within the column which inturn is operatively connected to the turntable so that the turntable isrotated in response to rotation of the shaft 6. The shaft 6 is alsoeffective when rotated to effect rotation of a vertically extendingshaft 9 which is drivingly connected to mechanism (not shown) in thecoiler head 1. Inasmuch as the coiler head forms no part of the presentinvention the details of construction thereof will not be described.

The transmission 7 includes a bevel gear 10 secured to the shaft 9 whichmeshes with a gear carried by the shaft 6. The shaft 9 is journalled byspaced bearings 11 carried by an extension 12 projecting horizontallyfrom the inner wall of the column 2. A gear 13 is fixed to the shaft 9in meshing engagement with a gear 14 secured to a shaft 15 which isjournalled by spaced bearings 16 supported by thel extension 12. Thetransmission 7 is drivingly connected to the gearing arrangement S bymeans of a drive shaft 17 which is located within the column 2.

In the present invention the drive shaft 17 is connected between thetransmission 7 and the gearing arrangement 8 by means of universaljoints 18 and 19 which permit adjustment of the shaft 17 for a purposeappearing hereinafter. The joint 18 includes an extension 20 detachablysecured to the lower end of the shaft 15 as viewed in Fig. 2, as by apress fit. The extension 20 projects into a recess formed in a fixture21 attached to the upper end of the shaft 17. A pivotal connection isprovided between the extension 20 and the fixture 21 so that the shaft17 may be pivoted about a horizontal axis relative to the shaft 15. Asimilar connection is provided between the shaft 17 and the geararrangement 8. As shown in Fig. 2, an extension 22 is detachably securedas by a press fit to the upper end of a shaft 23 with the extension 22being pivotally connected to a fitting 24 attached to the lower end ofthe shaft 17.

When the shaft 17 is rotated about its axis such rotation is impartedthrough the joint 19 to the shaft 23 which is journalled by spacedbearings 25 secured to an upwardly extending section 26 of the base 3.The shaft 23 has fixed thereto a gear 27 which meshes with an idler gear28 (Figs. 2 and 5) attached to an idler shaft 29 which is rotatablymounted by spaced bearings 26a carried by the section 26. As will appearhereinafter, the gears 27 and 28 may be selectively driven by adjustmentof the shaft 17 for permitting a change in the direction of rotation ofthe turntable.

At its lower end as viewed in Fig. 2, the shaft 23 has xed thereto abevel gear 30 which meshes with a bevel gear 31 secured to the left handend of an elongated worm shaft 32 which extends horizontally through an3 opening 33 of the base 3 beneath the turntable 4. The shaft 32 isjournalled by spaced sections of the base 3 and carries a worm 34 whichmeshes with a worm gear 35 secured to the turntable therebeneath, asbest shown in Fig. 4.

The gear 35 is secured as by screws 36 to a support 37 which is attachedby screws 38 to the turntable 4. The gear 35 and the turntable 4 aremounted for rotation as a unit with respect to the base 3 by a bearingarrangement 39 including a circular outer bearing race 40 which iscarriedby the support 37 and a circular inner bearing race 41 supportedby a block 42 in spaced relation with the race 40. Bearing balls arepositioned in the space between the races 4t? and 41 to complete thebearing arrangement. The block 42 is attached to the base 3 so that whenthe shaft 32 is rotated the gear 35, the outer race 40 and the turntable4 will be rotated as a unit relative to the inner race 41, the block 42,and the base 3.

According to the present invention the turntable 4 is arranged foradjustment relative to the base 3 and relative to the coiler head 1 sothat various sized sliver cans may zbe properly positioned with respectto the coiler head. The turntable 4 is configured so that sliver cans ofdifferent diameters may be supported thereby. In Fig. 4 a sliver can 5is illustrated in broken lines as `being supported by the turntable.However, a sliver can of smaller diameter than that illustrated may becarried by the turntable by means of an annular groove 4' formed in theturntable for receiving the lower edge of the smaller can. A sliver canof larger diameter than that illustrated may be supported by anattachment 4a detachably secured to the turntable 4 and having anannular groove 4b to receive the lower edge of the larger can. Theattachment 4a may comprise a plurality of separate grooved attachments,if desired. It is apparent that the turntable can be designed to supportsliver cans having various diameters.

In order to permit adjustment of the turntable, the -block 42 isadjustably carried by thebase 3 by means of a screw 43 extending throughan opening 44 of the block 42 into threaded engagement with a member 45of T-shaped cross section having its crosshead portion 45 positionedwithin a crosshead portion 4-6' of a horizontally elongated T-shapedslot 46 formed in the base 3. In Fig. 4, the block 42 is shown clampedto the base 3 by means of the screw 43 and the member 45 which has itsportion 45 drawn upwardly into tight engagement with a shoulder of thebase 3.

If it is desired to adjust the turntable 4, it is only necessary -torotate the screw 43 to loosen the member 4S and rotate the shaft 32 inthe proper direction so that the member 45, together with the block 42and the turntable 4, may be moved along the slot 46 in the desireddirection to any selected position along the length of the VWorm 34. Theblock 42 then may be clamped to the base 3 by tightening the screw 43.It is noted with reference to Fig. 3 that the direction of adjustment ofthe turntable 4 is parallel to the direction of extension of the wormshaft 32 and that the adjustment is conveniently effected without thenecessity of removing the shaft 32 and the gear 3S from their operativepositions, and disengaging the worm 34 and the gear 35. To effect 'theadjustment the turntable is moved in the desired direction along theslot which causes the gear 35 to rotate along the worm 34. Theadjustment may also be made by holding the gear 35 against rotation androtating the worm 34 to therefore effect movement of the gear 35 and theturntable along the slot 46. As best shown in Fig. 3, the slot 46terminates at its right hand end in a circular opening 47 through whichthe member 45 may be withdrawn to allow detachment of the turntable 4from the base 3.

As described previously, the worm shaft 32 is driven through bevel gears30 and 31 from a shaft 23. In the present invention the direction ofrotation of the shaft 32 and of the turntable 4 resulting from a givendirection of rotation of the shaft 17 may be reversed by driving theshaft 23 and the gear 27 from the idler gear 23 rather than directly asillustrated in Fig. 2. As shown in Fig. 2, the gear 27 is drivendirectly from the shaft 17 to establish a given direction of rotation ofthe turntable for a given direction of rotation of the shaft 17. Thisdirection of rotation of the turntable may be reversed without reversingthe direction of rotation of the shaft 117 by merely detaching theextension 22 from the shaft 23 and attaching the extension 22 to theupper end of the idler shaft 29 as shown in broken lines. Suchadjustment of the shaft 17 to the broken line position is permitted bymeans of the joints f8 and i9 and is readily accomplished manually. Theextension 22 may be exposed for the adjustment through an opening of thecolumn which may be normally closed by a suitable closure.
